摘要:
The invention described herein provides biocompatible molecularly imprinted polymers (MIPs) that are non-toxic, water soluble, small molecular weight, and degradable in a living body. The MIPs are capable of binding to all or a portion of a specific target macromolecule associated with a disease located within the living body and they are derivatized for stealth for in vivo applications to avoid the reticuloendothelial system. The MIPs of the invention are functionalized to an amine or carboxyl group and are derivatized with an imaging and/or therapeutic agent for taking images of the disease and/or for providing therapy. The macromolecule can be selected from a group consisting of proteins, glycoproteins, lipoproteins, peptidoglycans, peptides, polypeptides, polynucleotides, and polysaccharides. The invention described herein also provides methods and kits wherein MIPs of the invention can be employed as targeted imaging and therapeutic agents.
摘要:
A method for establishing a magnetic resonance system actuation sequence is described. A first number of field distribution maps are acquired for slices of the measurement region, and a radiofrequency pulse train is established on the basis thereof for the magnetic resonance system actuation sequence. This acquisition of the first number of field distribution maps may be brought about on the basis of an acquisition scheme. A reduced number of field distribution representation maps are established on the basis of the acquired field distribution maps, which field distribution representation maps represent the first number of acquired field distribution maps in accordance with a predetermined optimization criterion, and the radiofrequency pulse train is established on the basis of the field distribution representation maps.

A method is disclosed for determining a branching point within a hollow organ in image data representing the spatial structure thereof. In at least one embodiment, the method includes setting a start point within the hollow organ; determining at least one local threshold which corresponds to the presence of a wall of the hollow organ; carrying out a region growing method using the threshold; analyzing the connectivity of a number of outer growth layers; and localizing a branching on the basis of the connectivity analysis. Moreover, at least one embodiment of the invention relates to a correspondingly designed branching determination unit.

There are a multiplicity of methods of making through-holes. In particular in the production of a multiplicity of film-cooling holes, as in gas turbine blades or combustion chamber elements, small time advantages are also important when making a hole. The method according to the invention, to make the hole close to the final contour in each case in sections in a top and a bottom region in order to then produce the final contour with other laser parameters, achieves time advantages.

Methods, kits and compositions are described that include a non-naturally occurring kallikrein inhibitor and an anti-thrombolytic agent, e.g., an anti-fibrinolytic agent, for preventing or reducing blood loss and/or ischemia, e.g., ischemia associated with perioperative blood loss and cerebral ischemia, the onset of systemic inflammatory response, and/or reperfusion injury, e.g., reperfusion injury associated with cerebral ischemia or a focal brain ischemia, e.g., in patients subjected to invasive surgical procedures, especially procedures requiring cardiopulmonary bypass.
摘要:
There is described a method for producing a hole using e.g. a lasers, wherein short laser pulse durations are used. The laser pulse durations are varied, short laser pulse durations being utilized only in the area to be removed in which an influence on the penetration behavior and discharge behavior is noticeable while longer pulse durations of >0.4 ms are used. This is the case for the inner surface of a diffuser of a hole, for example, which can be produced very accurately by means of short laser pulse durations.

Conventionally coated components with film cooling holes are known, comprising a diffuser, extending through the layers into the substrate. According to the invention, the component is embodied such that the whole diffuser is largely arranged in the layer.
摘要:
Previous methods for the production of a hole in a component are very time-consuming and expensive, as special lasers having ultra short laser pulse lengths are used. The inventive method varies laser pulse lengths and ultra short laser pulse lengths are used exclusively in the region which is to be removed, wherein it is possible to have a noticeable influence on through flow and/or out-flow behavior. This, for example, the inner surface of a diffuser of a hole, which can be produced in a precise manner using ultra short laser pulse lengths.
